Ft. Lauderdale, FL - September 6, 2005 - Ener1, Inc. (OTCBB:ENEI) announced today that its board of directors has authorized a plan to spin-off the common stock of its three primary alternative energy subsidiaries to the Ener1 stockholders. The Ener1 board believes that each of EnerDel, NanoEner and EnerFuel has made significant progress in developing their technologies and business strategies such that each of these companies could successfully achieve its business plan as a stand-alone company. The Company's board has instructed senior management to implement the proposed plan to spin-off Ener1's interest in each of EnerDel, NanoEner and EnerFuel.

Any spin-off of these Ener1 subsidiaries will be subject to the receipt of applicable regulatory and third-party approvals and adequate financing, which Ener1 may seek in the public or private equity or debt markets. If the Company is able to satisfy these conditions, it anticipates that the board would declare a dividend to distribute the stock of its three operating subsidiaries within the next six months. As a result of this distribution by Ener1 to its shareholders, EnerDel, NanoEner and EnerFuel would each become a public reporting company under federal securities laws. In this regard, the Company will adjust the capitalizations and the number of outstanding shares of each spun off company so that each will have the ability to more easily qualify for listing at appropriate exchanges.

CEO Kevin Fitzgerald said, "Our three operations – EnerDel, NanoEner and EnerFuel – are alike in that they all concentrate on renewable power sources and related technologies. But they need to go in different directions now. They need to have access to capital and to be able to find strategic partners who can maximize the potential of their technologies. We believe the best way to accomplish this is to spin off the three 'pure plays' to the existing shareholders, subject to ensuring that each company is adequately capitalized. We believe all three companies will have excellent management teams, comprised in part by Ener1 executives, who will stand them in good stead."

EnerDel Inc., Ener1’s lithium battery business, has a new team of lithium specialists who are developing an advanced, high-rate battery primarily for the hybrid electric vehicle (HEV) market. As we announced on June 29, 2005, EnerDel is working with EnerStruct, a joint venture formed by Ener1 and ITOCHU Corporation, to consolidate its lithium Battery production facilities in Ft. Lauderdale and implement a new, automated manufacturing process developed by EnerStruct. EnerDel believes this new mobile, module type process will make its battery production operations more cost-competitive, as well as locate them closer to HEV manufacturers and other potential EnerDel customers with US production operations.

NanoEner Inc. has developed a proprietary technology for the production of nanostructured thin-film coatings for use in battery electrodes. NanoEner plans to expand its unique platform technology into other markets for nanomaterials, including thin-film photovoltaic solar cells, fuel cell components, super capacitors and thin-film sensors. NanoEner has built and is operating four prototype machines that produce samples of battery electrodes that demonstrate the capabilities of NanoEner’s technologies.

EnerFuel Inc. is positioned to address the needs of the fuel cell market in the near future. It has developed unique test fixtures and components that it is marketing to other fuel cell manufacturers. EnerFuel has won an innovative partnership with the State of Florida to develop a direct methanol fuel cell to power a rest area along a Florida highway and act as a test bed and demonstration platform for EnerFuel’s renewable energy technologies. EnerFuel’s long-term plans also include developing its proton exchange membrane fuel cell control system to provide high reliability, long life-time and safety of fuel cell-based power sources.

“We are confident that these subsidiaries are ready to become independent companies,” said Fitzgerald. “We believe that the shareholders of Ener1 would benefit through ownership of stock in three companies each pursuing different market opportunities in the alternative energy industry.”

In addition to receiving shares in the three companies, Ener1 shareholders would retain ownership of their Ener1 common stock, which would seek new investments in technology following the proposed spin-off.

Mr. Fitzgerald commented further that “Our first priority is to secure sufficient financing for the proposed transaction, and we intend to act expeditiously to accomplish this. We believe that the technologies and intellectual property of EnerDel, NanoEner and EnerFuel make them compelling investment opportunities.”
